Abstract (en)
[origin: EP0740400A1] The vehicle alternator comprises a fan which causes a flow of cooling air through the alternator body (10) between an input (44) where fresh air is drawn in, and an output (42) where air is expelled after heating by contact with the active components of the alternator. A radially projecting wall (48) is provided on the outside of the casing of the alternator. This part of the casing may consist of an end cover provided to protect the alternator components. The wall lies between the air inlet and air outlet in order to prevent the looping around of air between the outlet and inlet. This ensures that fresh air is drawn in continuously in order to ensure efficient cooling.
